A man killing weeds with a propane torch reportedly sparked a fire on Sunday that engulfed an exterior wall of his home west of Wilsonville, according to Tualatin Valley Fire & Rescue.

Firefighters arrived around 12:24 p.m. to a home near Southwest Tooze Road and Southwest Grahams Ferry Road where fire was climbing up exterior side and into the attic space, authorities said.

The fire was controlled quickly and firefighters rescued a dog from inside the home. The residents were safely evacuated.

Authorities said the fire was sparked when a resident of the home ignited a pine tree on the side of his house with a propane torch he was using to kill weeds. The man told authorities he wet down the tree before he started working around it, but the tree ignited anyway.

"This fire is an unfortunate reminder of the need for serious caution and restraint when operating an open flame anywhere near a dwelling, particularly when the conditions are dry," said Tualatin Valley Fire and Rescue spokesman Walt Peck.

The fire caused significant damage to the roof, and water and smoke damage was found in the living areas of the home. Damage estimates are not available at this time.
